Properties

Learn to control access to class fields using properties.

We'll cover the following...

In C#, there are regular and special methods that control access to class fields. These methods are called properties.

Properties are created with the following syntax:

// Like other members, properties can have acess modifiers
[access modifiers] property_type property_name
{
    get
    {

    }
    
    set
    {
        // Set block contains actions to perform when setting the value of the field
    }
}

Properties don’t hold any value. They only act as intermediaries between the external code and the fields.

Let’s look at an example.

using System;
namespace Properties
{
    class Program
    {
        static void Main(string[] args)
        {
            Car car = new Car();
            car.Model = "Lexus LS 460 L";
            car.Price = 65000;
            Console.Write($"{car.Model} costs {car.Price} dollars");
        }
    }
}

Here, the Car class defines the private model and price fields that store the model and the price of the car. Along with these fields, there are two public properties called Model and ...
